APPARATUS FOR BURNING HYDROCARBON OILS.

SPECIFICATXON forming part of Letters Patent No. 3&6A6, dated August 3, 1886.

Application filed January l2, 1886. Serial No. 188,328.

T0 all whom, it may concern,.-

Beit known that I, EDWARD C. BURGEss', a citizen of the United States, residing at 643 North Thirty-fifth street, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Apparatus for Burning Hydrocarbon Oils, of which'the following is a specification.

My invention relates more particularly to such apparatus as applied for generating steam and heating large areas; and the object of my improvement is to overcome the difficulties experienced in other apparatus by the elogging of retorts and pipes, the destructive act-ion of the intense heat, the unsteady action of the tire, andthe need of an auxiliary boiler to supplysteam for the apparatus,all of which are by my improvements entirely avoided. I attain these objects by the mechanism illustrated in the accompanying drawings7 in which- Figure l is a vertical section of a steamboiler, showing the entire apparatus as placed therein. Fig. 2 is another boiler, showing a different form of baiiler to form combustionchamber. Fig. 3 is a wateriilter,'which can be Very simply attached to the apparatus.

Letters in each view indicate the parts referred to in the specification.

In Fig. l, B is a section of a boiler. \V is a water-pipe, having two sources of supply-one through branch D from either a main or pressure-tank, the other through branch A from the boiler. This pipe, having two valves, E F, leads to a filter, G, (see Fig.3,) and needle-valve H; thence, passing into the furnace, is carried along the right side, constantly descending to the back or baffle wall, L; thence clear across the furnace to left side; thence out through draft-opening to an air or steam chamber, l. O is an oil-pipe, which, from any source of supply, leads to needle-valve J, thence into furnace and out to in jcctor K. Either the water or oil pipe may be any shape adapted to the furnace employed. L isa bafe-plate or back wall composed of tire-brick or any such refractory material; M, a shelf or apron connected to the waterspace of the boiler, which apron and fire-brick wall, eX- tending across the lire-box, form both a combastion-chamber for the more complete union (No model.)

of the gases, and also serve to distribute the flame to every part of the furnace.

Fig. 2 is intended to represent a boiler of ordinary construction, which is not provided with a water-apron or detlector. In such boilers I place a wall of tire-brick, &c., and across the top of the wall lay slabs of the same material,substantially in the mannershown. 'This acts like the water-apron in Fig. l, but does not, like the apron,add more heating-surface. Itis, however, equally as good as a detlector and combustioil-chamber.

Fig. 3 represents a filter formed by simply rolling very tine brass wire-gauze into cylindrical form and filling the water-pipe WT. The wire-gauze, extending through the T and partially into a capped pige, P, can, by unscrewiug the latter, be readily drawn-Outland cleaned. Its object is to prevent dirt and Vegetable matter in the water from clogging either needlevalve H or pipe H P.

In making a lire, the operation is as follows: A few sticks, shavings, or pieces of greasy waste are thrown in upon several parts of the pipe H P and ignited. After they have burned thereon a few minutes, open the valve F, letting water from pressure-tank or m'ain to necdle-valve H. Gently and slightly open needle-valve H, and a tine stream of water passing into the new hot pipe H P is converted into steam, and entering steam -chalnber I passes from it into the outer cylinder of injector K, from which it issues as a tine cylinder of steamwith great force. The needlevalve J is then opened, and the oil passing into pipe H O enters the interior of injector K, where it is caught by the rushing steam and hurled with great force against the slab or wall L. The vapor thus formed being ignited bythe material still burning on the pipe H P, the whole tire-box is iilled with llame, which, heating the pipes H Pand H O, increases their effectiveness until a dry superheated steam is hurling a fluid mostly vapor and gas, instead of oil, into the furnace. The force of impact breaks into line particles any oil not already made vapor by heat.

vacuum produced by the force of the ictdraws into the center of llame 'a strong current of air, so that the hydrocarbon vapor, the superheated steam, and air are thoroughly interrPhe roo

mixed, and the combustion chamber holds them until their combination is complete7 the result, with any kind of oil, being a pure and smokeless tire.

As it is desirable to use the least possible amount of piping within the furnace, so that it may be fully protected from heat by the wal ter and oil passing through it, I add the chamber I to increase the cubic area, and thus by the elasticity of the steam secure a steady and regular flow from the injector K.

After a suficient pressure of steam is generated in the boiler B, the valve E is opened, allowing the hot Water at the boiler-pressure to flow into pipe I-I P, and valve F and' press-V u1'e-tank,having served their purpose of starting the tire, are shut off.

I am aware that the combination of a bafile.- plate backed by a Water-chamber and surinounted by a shelf of refractory material is not new, and this I disclaim.

I am aware that pipes, injectors, Snc., have been used for similar purposes prior to my invention, and I- do not claim them, broadly; but

What Ido claim as my invention, and desire to secure by Letters Patent, is-

l. In an'apparatus for burning hydrocarbon oils` the combination of an inlet-pipe,W, with a filter, G, a heating pipe or coil, H P, an equalizng-chamber, I, and an injector, K, all substantially as shown.

2. In an apparatus for burning hydrocarbon oils, the combination of a Watershelf or apron, M, with a bafe plate or wall, L, and injector K, substantially as shown.

3. The combination of the heating-coil H P, equalizing'chanlber I, and injector K, substantially as shown and described.
